Pulse water flow forming system driven by hydraulic power of fountain and surf

The invention relates to a pulse water flow forming system driven by the hydraulic power of fountain and surf. Water enters a branch pipe through a main pipe and an air pressure storage tank after being pressurized by a water pump, enters respective capillary pipes in a manner of the pulse water flow with the pressure rising quickly and dropping slowly after passing though pulse valves in the front of the respective capillary pipes, and is jet in pulse manner through sprayers (nozzles) installed on the respective capillary pipes for people to appreciate and play. Jet water flows back to a water source to recycle after confluence, sterilization and filtering. As the pressure rises quickly while drops slowly, based on the design of the air pressure storage tank, jet water flow has the characteristics of strong explosive force, slow drop, good visual effect and strong appreciation. The pulse frequency can be regulated in a large range; the sprayers (nozzles) of different groups and different types can be driven through setting pulse valves at different frequencies, so that the jet water flow has changeable patterns, rises one after another, and is interesting. Compared with an electronically controlled system driven by electrical power, the system adopts simple structure, has good safety, needs low investment cost, and is easy to maintain and repair.

Method for planting fruit tree having different fruits at the same tree

The invention provides a cultivation method of one fruit tree with different fruits, the key is to select the trees which have homologous nuclear or homologous leaves or both of them as the parents for grafting cultivation of fruit trees, the grafting trees time is after the walking of insects and before spring equinox. Choose the fruit trees with clusters of branches having two years growth period or more as the rootstock, and choose the new branch which has the same origin with the rootstock and lives on the sunny side of high yield, strong fruit tree as the scion. Graft scions from many good fruit tree species to various rootstock branches of the same fruit tree, cultivate them carefully till survive, in current year and next year many fruits grow on the same fruit tree, in order to realize one fruit tree with different fruits. Various flowers bloom and many kinds of fruits grow on the same fruit tree, which not only has a lot of economic benefits, but also high appreciation quality. The produced fruits have rich nutrition, and taste well than the original variety. The invention not only make full use of fruit trees resource and land resource, but also reduce producing cost, and to some extent improve the ability of resisting the market risk and seasonal risk.

Novel bionic butterfly aircraft with independently driven double wings

InactiveCN105947196AGood bionicityCapable of military reconnaissanceOrnithoptersControl systemAerospace engineering
The invention discloses a novel bionic butterfly aircraft with independently driven double wings. The aircraft comprises a main body, wing assemblies, a micro-control system, and a power supply system. A servo motor bracket, a posterior wing connecting hinge, a controller connecting bracket, and a cell connecting bracket are installed on the main body from front to back, and are used for installing a servo motor, a posterior wing, a micro-control system, and a power supply system of the wing assemblies. The wing assemblies comprise a left wing assembly and a right wing assembly, the assemblies have the same structure and dimension parameter, and the assemblies are symmetrically installed on the left and right sides of the main body with the servo motor. The lift and thrust are generated by the flap movement of the left wing and right wing of the bionic butterfly aircraft controlled by the servo motor. The bionic butterfly aircraft realizes the no control surface aircraft control of double wings and double driving, and independently controls the flap frequency, amplitude, and beginning and end phase positions of two wings, so that the movement of pitching and yaw can be finished efficiently and stably by the bionic butterfly aircraft, and the autonomous flight of the bionic aircraft can be realized.

Fabric planted with silkworm cocoon or silkworm cocoon slice

The invention relates to a fabric implanted with silk cocoons or silk cocoon sheets, wherein, at least one layer of underlayer fabric 11 is implanted with the silk cocoons 12 or the silk cocoon sheets 13. The silk cocoons 12 are the natural silk cocoons 12 or the silk cocoons 12 treated with functional processing, and the silk cocoon sheets 13 are formed by that the natural silk cocoons 12 are divided into two pieces or more than two pieces of geometric form platelets. The silk cocoons 12 or the silk cocoon sheets 13 implanted on the underlayer fabric 11 are arranged in the form of a pattern, or loosely and randomly distributed, or tiled, or laminated by a plurality of layers. The silk cocoons 12 treated with functional processing are formed by that the interiors of the silk cocoons 12 are filled with fillers mixed with antibacterial or anthelminthic or fragrant microcapsule finishing agents, or the surfaces of the silk cocoons 12 or the silk cocoon sheets 13 are drawn or sprayed with multicolor superfine snowflake grain shape patterns formed by microcapsule dye liquid droplets internally containing a plurality of colors and auxiliary agents. The fabric of the invention is completely different from the current classical method which obtains raw silks from the silk cocoons by silk reeling so as to weave silk cloth, and directly implant the silk cocoons on the underlayer fabric to lead the fabric to have new and unique visual effect, thus meeting the trends of individuation, fashion-orientation and innovation and variety seeking of the fabrics.

General video digital watermark method

The invention discloses a general video digital watermark method mainly comprising analysis, embedding and extraction processes of a system design scheme. The analysis of the system design scheme comprises determination of a system function, watermark algorithms Ai to be embedded, embedding proportions of all algorithms and minimum extraction frame number Fmin; the watermark embedding process comprises frame distribution of a video file, watermark information pre-processing, embedding of watermark algorithms and formation of video files containing watermarks, wherein the embedding of watermark algorithms comprises the steps of: calculating embedding frame numbers, selecting embedding frames and embedding the watermark; and the watermark extracting process comprises frame distribution of the video file, selection of video frames to be detected, extraction of watermark information and calculation similarity. In the invention, the plurality of watermark algorithms are embedded at the same time and the embedding proportions can be selected, thereby the watermark method obviously enhances attack-resistant property; the watermark embedding ensures the appreciation and the embedding speed of the video file by using a non-frame-by-frame embedding way; in the watermark extracting process, the number of the detecting frames is less and the detection efficiency is improved; in addition, the general video digital watermark method also intensifies the capability of resisting frame edition.
